Excerpt: Just recently awarded “ Best Power Supply Manufacturer of 2008 ” by Custom PC, Corsair is a familiar name to those who have been building computers for any length of time. Known for years as a major player in the enthusiast computer memory industry, the company branched out in 2006 and began selling branded power supplies.
Summary: Corsair HX620W is a terrific power supply and won’t let you down. In our tests it could really deliver its labeled power at 50° C, showed a terrific voltage regulation, it was very quiet, produced a very low electrical noise level and its efficiency was of at least 83%, peaking 88%. And the best of all: we could extract up to 746 W from it. So you will be basically paying for a 620 W product and bringing home a 740 W power supply.
Summary: Flashy hardware like LED lights, special illuminated fans, plexiglass windows, chrome plating and modular cable systems do nothing. Corsair's HX620W power supply certainly has many good things going for it.
Conclusion: At previous page you saw some points why to buy and not to buy Corsair HX620W power supply, but overall it is a great product. Remember that in the tests we overloaded the power supply by almost 80 per cent. The only really bad result in the tests was the power factor correction. Sadly we couldn't measure the effective power factor because of lack of some dedicated (expensive) equipment.
Pros: Triple 12 volt rails, Cable ties included, Squeeze'n'pull connectors
Conclusion: Corsair has proved to be a top choice for quality desktop PSU with their HX series and their top of the line HX620W modular power supply marks the companyâ€™s entry into the PSU market. The overall impression was top class and we couldnâ€™t ask for a better packaging. We also liked the fact that the PSU was well protected and this shows Corsairâ€™s interest in delivering a defect free product to the customer.
Pros: Great packaging, Silent, Stable voltages, Modular cables , Lightweight and fits almost any PC case, Not too expensive, 5 years warranty
Summary: The new Corsair PSUs are not only aimed at the power-demanding PC gamer, but also the growing class of quiet PC enthusiasts who also want to be able to run some seriously powerful gear. The HX620W and HX520W deliver clean, ultra-stable power under a wide range of demanding conditions. They also happen to be about the quietest fan-cooled PSUs we've tested to date, matching the best of the Seasonic S12s.
Summary: Corsair has ventured even further away from their home range landing in the middle of Power Supply territory. Their initial offering´s are well constructed and feature one of the best modular cable systems seen to date. Today we have the opportunity to test their CMPSU-620HX modular PSU.
Conclusion: This is a very stable PSU with stable rails and a quiet fan, I don’t think there is much more you can ask for. Corsair have really transfered their high quality from their memory to their PSU also. I am quiet surpised also over how silent this PSU actually is, it’s one of the most silent ones I have ever reviewed if not even the most silent. Overall the quality is high, the connectors lock on well and they are easy to remove.
